“…Based on the broken‐line regression analysis for SGR, the appropriate concentration of EAE for growth of carp was estimated to be 3.544 g/kg diet. The improvement in growth may be partly attributed to the development of digestive organ in fish (Hong et al, ). In this study, the significant increases in the hepatopancreatic weight, HSI and HPC as well as the intestinal weight, ISI and IPC were observed in carp fed with diets contained EAE for 60 days.…”

“…The growth of fish is related to FI (Zhou, Zhao, & Lin, ). The FI of fish is closely associated with the activities of enzymes related to digestion and absorption (Hong et al, ). Trypsin, lipase and amylase in the hepatopancreas and intestine play a key role in digesting nutrients for fish, of which the activity can directly reflect the digestive ability of fish (Ling et al, ).…”

“…Elevated Cu concentrations can induce the overproduction of ROS (Sevcikova, Modra, Slaninova, & Svobodova, ) that can react at a high rate with the most of biologically important molecules, such as lipid, proteins and nucleic acids, and thus damage cellular function in aquatic animals (Lushchak, ). The intestine and hepatopancreas are the important organs for nutrient digestion and absorption in fish (Hong et al, ). However, it has been reported that Cu accumulates mainly in the intestine and hepatopancreas of fish (Hoyle, Shaw, & Handy, ; Kamunde, Grosell, Lott, & Wood, ).…”

The study explored the effects of ethyl ether extract, ethyl acetate extract (EAE), acetone extract, ethanol extract and aqueous extract of Angelica sinensis (EAs) and ethoxyquin (EQ) on lipid oxidation in erythrocytes and growth, digestive, absorptive and antioxidant capacity in carp (Cyprinus carpio var. Jian). The results indicated that EAs and EQ respectively at the concentrations of 0.5 and 0.25 mg/ml suppressed lipid oxidation by decreasing the generation of ROS and restoring the activities of antioxidants in hydroxyl radical-treated erythrocytes. Of all of the examined EAs, EAE showed the strongest protective effects against lipid oxidation in carp erythrocytes. The antioxidant effects of EQ at the concentration of 0.25 mg/ml were stronger than that of EAE at the concentration of 0.5 mg/ml in fish erythrocytes. The antioxidative activities of EAs in carp erythrocytes were positively correlated with their phenols content. Moreover, dietary EAE raised growth performance in fish. The appropriate concentration of EAE for the growth of fish was estimated to be 3.544 g/ kg diet. Dietary EAE increased digestive and absorptive capacity in carp and improved antioxidant capacity in copper-treated carp. So, EAE could be used as a potential natural antioxidant and inhibitor of copper stress in fish.

“…Tang et al (2013) showed that the increase in the activity of antioxidant enzymes in the intestine of the young grass carp Ctenopharyngodon idella is related to decrease in lipid peroxidation and protein oxidation, resulting in enhanced intestinal defense. Similar to colostrum, amino acids also increase the intestinal activity of antioxidant enzymes (Li et al, 2014;Hong et al, 2015). Jiang et al (2010) also observed that the inclusion of components that inhibit free radical generation (myo-inositol) in the diet of Jian carp (Cyprinus carpio var.…”

ABSTRACT. Besides the immunological benefits of colostrum consumption, this lacteal secretion has a great concentration of biological molecules that can affect gut physiology and fish healthy. This study evaluated the antioxidant potential in the gut of juvenile pacu, Piaractus mesopotamicus, and dourado, Salminus brasiliensis, fed twice a day with diets containing 0, 10 or 20% of lyophilized bovine colostrum (LBC). The whole medium and posterior intestine was collected after 30 or 60 experimental days and the activity of catalase, superoxide dismutase and glutathione peroxidase was determined as one international unit per milligram of protein, and the oxygen radical absorbance capacity as µM of equivalent Trolox per milligram of protein. Only the juvenile pacu were affected by the diet containing LBC (P < 0.05). The juvenile fed 10% LBC showed higher oxygen absorbance capacity than the juveniles fed 20% LBC (P < 0.05). Interaction between diet and period was observed to superoxide dismutase (SOD) activity (P < 0.05), juvenile pacu fed 0% LBC and 10% LBC did not change enzyme activity at 30 and 60 days, whereas juvenile fed 20% LBC showed higher value at 60 days compared to 30 days (P < 0.05). The present result reveal that the consumption of diet containing LBC improved SOD activity in the gut of juvenile pacu indicating a possible protective action of this lacteal secretion in an omnivorous fish.

Firstly, a linoleic and linolenic acid emulsion and fish feeds were incubated with graded levels of ethoxyquin (EQ) and petroleum ether extract, ethyl acetate extract (EAE), ethanol extract and aqueous extract of Angelica sinensis. The results showed that EQ and extracts of Angelica sinensis (EAs) inhibited lipid oxidation in material above. Of all of the examined EAs, EAE showed the strongest protective effects against the lipid oxidation. Moreover, EAE at high concentrations showed a stronger inhibitory effect on lipid oxidation than that of EQ. Next, 7 experimental diets that respectively supplemented 0.0, 0.2, 0.8 and 3.2 g kg of EQ and EAE were fed to 280 juvenile red carp (Cyprinus carpio var. xingguonensis) with seven treatment groups for 30 days. The results indicated that dietary EAE improved growth performance in carp. Moreover, dietary EAE increased the activities of trypsin, lipase, alpha-amylase, alkaline phosphatase, glutamate-oxaloacetate transaminase and glutamate-pyruvate transaminase (GPT) and decreased plasma ammonia content in carp. Meanwhile, dietary EAE reduced the levels of malondialdehyde and raised the activities of anti-superoxide anion, anti-hydroxyl radical, superoxide dismutase, catalase, glutathione peroxidase and glutathione reductase and the content of reduced glutathione in the hepatopancreas and intestine of carp. However, with the exception of GPT, dietary EQ got the opposite results to dietary EAE in carp. These results revealed that dietary EAE improved the digestive, absorptive and antioxidant capacities in fish. However, dietary EQ inhibited the digestive, absorptive and antioxidant capacities in fish. So, EAE could be used as a natural antioxidant for replacing EQ in fish feeds.
